About Frontiers of the Roman Empire – Dacia

A component of the UNESCO Frontiers of the Roman Empire that covers Roman military and civilian sites marking the northern frontier of the province of Dacia in present-day Romania. The surviving remains include forts, towns and road networks associated with Roman military control.

Ruins at key centres show defensive earthworks, stone fortifications, and traces of urban layouts including forums and public buildings. Excavated sites display building plans and artefacts that reflect military, administrative and economic activities along this frontier.

Most frontier works in Roman Dacia were established after the Dacian Wars in the early 2nd century AD as Rome consolidated control over newly annexed territories. The frontier evolved through the 2nd and 3rd centuries with a mix of permanent forts and associated civilian settlements.

The inscribed sites are located in northwestern and central Romania, including Sălaj County and neighbouring areas, set within a landscape of hills and river valleys that formed natural lines for frontier emplacement.

  • Date range and character: Sites represent the northern frontier of Roman Dacia and include forts, military camps and linear frontier works dating chiefly to the 2nd and 3rd centuries AD.

What to See#

  • Porolissum: The monumental Roman town of Porolissum, originally established as a military complex on the northern edge of Roman Dacia, with remains of a forum, theatre and defensive works dating mainly to the 2nd and 3rd centuries AD.
